## What is a belt scale?

A belt scale is used to continuously measure and report flow rates and totalized amounts of materials being transported on a conveyor belt. The weight of the material transported is determined by weighing the belt load and measuring the belt speed.

How does a belt scale work?

Conveyor belt scales weigh the material and determine the rate at which material travels on a conveyor belt over a specific period of time. Once the static weight is measured, the integrator incorporates the weight with the speed at which the belt is rotating to calculate the rate of mass per time.

How accurate are belt scales?

Some belt scale systems provide basic rate information and totalization functions in processes involving non-critical or lower value materials with an accuracy of ±1%. Most belt conveyor scales are capable of providing reliable results within ±½% of their full-scale rating.

### What is a conveyor belt scale?

Belt scale conveyers are an important part of most bulk material handling facilities. A belt conveyor scale system monitors raw material feed to crushers, mills, screens, preparation plants, and coal-fired power plants to help ensure precise feeding of process materials and maintain product quality.

What is a weigh feeder?

Weigh feeder is a closed-loop control system, which controls the flow of material very accurately using controller and different instruments. This system accepts an external command from process computers like SCADA, HMI, DCS etc.

How do you calculate the TPH of a belt conveyor?

CAPACITY (TPH) = . 03 x Belt Speed (FPM) x material weight (lb. per cu. ft.)

#### What is a belt scale integrator?

It accurately monitors belt travel and loading (HzLd weigh frame load cells) to compute tonnes/hour, meters/sec and total tonnes. Diagnostics monitor input parameters and provide failsafe “Scale OK” confirming correct operation of the conveyor belt scale.

How does a conveyor belt Weightometer work?

A belt weigher is used to determine the mass of the material transported on a conveyor belt. The weight of the material transported is determined by weighing the belt load and measuring the belt speed. The belt speed remains constant while the feed rate is regulated by varying the belt loading if required.

How does weighing conveyor work?

## How does a weigh belt feeder work?

Weigh belt feeders operate by continuously weighing a moving bed of material on its short conveyor, and controlling belt speed to result in the desired flow rate at discharge. Therefore, weigh belt feeders can achieve high rates while remaining compact. Open frame models are typically used in food applications.

What are the features of a belt scale?

The unique parallelogram-style load cells ensure minimal hysteresis and superior linearity, and ignore all horizontal forces. All belt scale designs feature overload protection for the load cells. Reliable motion failure alarms (MFA) provide added proection detecting changes in motion and speed of your conveying equipment.
